To provide a vehicle lighting device capable of reducing deterioration and maintaining visibility.SOLUTION: A vehicle lighting device includes: a light emission unit that illuminates a road surface in the outside of an entrance of a vehicle to be opened and closed; and a control unit that detects brightness of the outside when the entrance is opened, and causes the light emission unit to light when the brightness in the outside is equal to or less than a predetermined value. The control unit may change the brightness of the light emission unit according to the brightness of the outside. The light emission unit has the maximum value of brightness of the light emission unit. The control unit causes the light emission unit with brightness of the maximum value when the brightness of the outside is equal to or greater than the predetermined value.SELECTED DRAWING: Figure 4

    【課題】劣化を低減し視認性を維持できる車両用照明装置を提供する。【解決手段】車両の開閉される乗降口の外側の路面を照明する発光部と、乗降口が開いた場合外側の明るさを検出し、外側の明るさが所定値以下である場合、発光部を点灯する制御部と、を備える。制御部は、外側の明るさに応じて、発光部の明るさを変更してもよい。また、発光部は、発光部の明るさの最大値を有し、制御部は、外側の明るさが所定値以上である場合最大値の明るさで発光部を点灯する。【選択図】 図4
